Abstract

The invention discloses a method, a system and equipment for optimizing cell reference symbols. The method comprises the following steps that: a network node receives a measurement event from UE; the network node determines the information of the UE according to the measurement event; and the network node optimizes the cell reference symbols of the UE according to the information of the UE. The coverage condition of the cell reference symbols is acquired by using the measurement event of the UE, and the cell reference symbols are optimized and the transmitting power of the cell reference symbols is adjusted according to the coverage condition so as to fulfill the purpose of automatically optimizing the cell reference symbols; and the cell reference symbols can be accurately optimized without modifying a protocol.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method, system and equipment for optimizing cell reference symbols. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the evolution of 3G (3rd Generation, third-generation mobile communication system), LTE improves and enhances 3G air access technology, adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) Use) and MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output) as the only standard for wireless network evolution. LTE can provide a peak rate of downlink 100Mbit / s and uplink 50Mbit / s under 20MHz spectrum bandwidth, which improves the performance of cell edge users, increases cell capacity, and reduces system delay. In the LTE system, an RS (Reference Symbol, cell reference symbol) is introduced. According to the RS, the terminal can perform channel estimation and cha...
